Hi! On my new HDD WD30EZRX I created a GPT partition table and formatted it with XFS. Then I put some data (approx. 2.4TB) on that new partition. However, after restarting the system the disk is identified of size 2TB only. /knoppix@Microknoppix:~$ sudo fdisk -l Disk /dev/sda: 2000.4 GB, 2000421444608 bytes 255 heads, 63 sectors/track, 243204 cylinders, total 3907073134 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes/ Checking the HDD with tool gdisk, I get this output for option "i" (show detailed information [...]): /Command (? for help): i Using 1 Partition GUID code: 0FC63DAF-8483-4772-8E79-3D69D8477DE4 (Linux filesystem) Partition unique GUID: 37786D32-C98F-4624-9440-94F79BE79793 First sector: 2048 (at 1024.0 KiB) Last sector: 5860533134 (at 2.7 TiB) Partition size: 5860531087 sectors (2.7 TiB) Attribute flags: 0000000000000000 Partition name: 'Linux filesystem'/ Using option "v" (verify disk) I get this output: /Expert command (? for help): v Caution: The CRC for the backup partition table is invalid. This table may be corrupt. This program will automatically create a new backup partition table when you save your partitions. Problem: The secondary header's self-pointer indicates that it doesn't reside at the end of the disk. If you've added a disk to a RAID array, use the 'e' option on the experts' menu to adjust the secondary header's and partition table's locations. Problem: Disk is too small to hold all the data! (Disk size is 3907073134 sectors, needs to be 5860533168 sectors.) The 'e' option on the experts' menu may fix this problem. Problem: partition 1 is too big for the disk. Identified 4 problems!/ My understanding of the issue is: 1. The HDD is not identified correctly by the mainboard/Bios with 3TB. This is confirmed by the hardware vendor of my mainboard "Gigabyte P35-DS4", means the limit is 2.2TB 2. The partition is too small to keep data of size 2.4TB How can I recover the data? Should I simply create a new partition table either with gdisk or parted? Can I make a low-level copy using dd starting from sector 2048 until the end to another HDD WD30EZRX (that I have available) and then mount that partition? Or are there any other options?
